| Gene Symbol | PLIN2 |
| Chromosome | 9p22.1 |
| Protein Type | Structural Protein |
| Target Class | Structural Protein |
| Function | Lipid Storage: Promotes triglyceride storage by facilitating lipid droplet formation and preventing lipolysis [@brasaemle2004] |
| Mechanism of Action | Direct PLIN2 inhibitors would reduce lipid droplet formation and stability, promoting lipid mobilization and reducing pathological lipid accumulation. Indirect approaches target upstream regulators of PLIN2 expression or modulate associated lipases to alter lipid storage dynamics in metabolic and neurodegenerative disease states. |
